function" from Anand K Mistry <amistry@google.com>:
This patchset adds support for being able to change regulator modes for
the mt6397 regulator. This is needed to allow the voltage scaling
support in the MT8173 SoC to be used on the elm (Acer Chromebook R13)
and hana (several Lenovo Chromebooks) devices.
Without a of_map_mode implementation, the regulator-allowed-modes
devicetree field is skipped, and attempting to change the regulator mode
results in an error:
[ 1.439165] vpca15: mode operation not allowed
Changes in v2:
- Introduce constants in dt-bindings
- Improve conditional readability
Anand K Mistry (4):
regulator: mt6397: Move buck modes into header file
dt-bindings: regulator: mt6397: Document valid modes
regulator: mt6397: Implement of_map_mode
arm64: dts: mediatek: Update allowed mt6397 regulator modes for elm

This will allow device trees to make use of these constants.

This patch refactors buck modes into a header file so that device trees
can make use of these mode constants.
The new header filename uses da9063 because DA9063 was the earlier chip
and its driver code will want updating at some point in a similar manner.

Add documentation for act8865 regulator modes and suspend states.
Add active-semi,8865-regulator.h file for device tree binding constants
for act8865 regulators.

The regulator supports a dedicated suspend mode.
Implement the appropriate ->set_suspend_xx() hooks, add support for
->set_mode(), and provide basic PM ops functionalities to setup the
regulator in a suspend state when the system is entering suspend.

Introduce bindings for RPMh regulator devices found on some
Qualcomm Technlogies, Inc. SoCs. These devices allow a given
processor within the SoC to make PMIC regulator requests which
are aggregated within the RPMh hardware block along with requests
from other processors in the SoC to determine the final PMIC
regulator hardware state.

Add a header file for the max77802 constants that could be shared between
the regulator driver and Device Tree source files. Also, remove standby
and off opmodes since only normal and low power are valid operating modes.
